Shared Air Pipe Layout for Compact Audio Equipment

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional air pipes in audio equipment occupy excessive space due to their independent configuration, leading to crowding within the device.

Innovation Solution

The audio equipment incorporates first and second air pipes that share a common wall, with distinct inlet and outlet orientations and configurations to minimize space usage, allowing for more efficient arrangement and reduced overall space occupation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If independent air pipes are configured for each loudspeaker unit, then audio signal guidance function is ensured, but space inside the audio equipment is excessively occupied

Engineering Contradiction:

Improveaudio signal guidance functionVSAvoidspace occupied by air pipes

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent merges two separate air pipes into a single integrated air pipe structure. The shared air pipe contains separate channels for guiding audio signals from different loudspeaker units, reducing the total number of air pipes from two to one while maintaining the independent signal guidance function for each loudspeaker unit.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The shared air pipe performs multiple functions simultaneously: it guides audio signals from the first loudspeaker unit through the first channel, and audio signals from the second loudspeaker unit through the second channel. This multi-functional design allows a single air pipe structure to replace what would traditionally require two separate air pipes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple independent air pipes are used, then each loudspeaker unit has dedicated signal path, but the internal space arrangement becomes crowded

Engineering Contradiction:

Improvededicated signal path for each loudspeakerVSAvoidspace arrangement complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The shared air pipe is segmented into multiple independent channels within its structure. The first channel is dedicated to guiding audio signals from the first loudspeaker unit, while the second channel is dedicated to the second loudspeaker unit. This segmentation maintains dedicated signal paths without requiring separate external air pipes for each loudspeaker.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements a nested structure where multiple signal channels are contained within a single air pipe body. The first and second channels are nested within the shared air pipe structure, allowing each loudspeaker unit to have its own signal path while the overall air pipe system occupies less space than multiple independent air pipes would require.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

An audio equipment includes a first air pipe and a second air pipe. The first air pipe includes a first audio inlet, a first audio outlet and a first wall. The first wall extends from the first audio inlet to the first audio outlet. The second air pipe shares the first wall with the first air pipe. The second air pipe includes a second audio inlet and a second audio outlet. The first wall extends from the second audio inlet to the second audio outlet, and the facing direction of the first audio outlet is different from the facing direction of the second audio outlet.
